To all whom it may concern: r

Be it known that I, LOUIS W. SOUTHGATE, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented a new and useful Improvement inElevator-Controllers, of which the following is a specification. The aimof this invention is to improve that class of elevator-controllers inwhich a contronlng 'Ope or ropesis or are connected to the elevator-carto travel therewith, a controlling-rope of this character being commonlytermed a running controlling-rope.

The common or ordinary way to arrange a I 5 running controlling-rope isto attach both ends thereof to the car or one end thereof to the car andthe other end to a weight which moves up and down with the car.

ling rope or ropes to the elevator-car, in using a take-up devicefortaking up or letting out the controlling rope or ropes as the cartravels, and in applying motor-controlling connections to saidcontrolling rope or ropes between the car and said take-up device. Byapplying the motor-controlling connections in this manner between thecar and the take-up device a very efficient mechanism is provided;because the running controlling rope or ropes 0 pass directly from thecarto said connections.

'Also by this construction a very short length 3 of controlling-rope canbe used and all over head work in the elevator-well for the con'-trolling rope or ropes can be done away-with.

5 In the preferred form of my invention the take-up device consists ofsets of stationary and movable devices operating with the sta-T tionaryand movable sheaves of one of the or-.

The mo- 1 My arrangement consists in attaching the control myconstruction I can attach the other end of the controlling rope or ropesto a fixed point and can there use any ordinary adj usting or tensioningdevice.

I will now describe my invention in detail,

and reference, to follow this description, should be had to theaccompanying two sheets f drawings, in which Figure l is a sideelevation of an elevator land motor arranged according to my invention.Fig. 2 isa plan of the motor and sheaves. @Fig. 3 is aside elevation ofa modification. Fig. 4 is a plan of the hoisting-drum and takefup deviceused in the modification shown in Fig. 3; and Fig, 5 is a view similarto Fig. 1,

illustrating how my invention can be carried .out with a single runningcontrolling-rope.

Referring to the first sheet of drawings, A

designates the elevator-car, and C the hoist.- 7o ging-cables, which areled over the ordinary overhead sheaves B and then down to the bottom ofthe well around a set of stationary sheaves D and a set of travelingsheaves E, which latter are mounted in a carriage F, which carriage isactuated by means of a piston-rod extending into and connected to agpiston moving in the cylinder G. Water is let into and out of thecylinder Gr by means of any of the usual valves V. This arrange- 8o mentis a common one and is well understood.

Mounted on or carried by the car are any -of the usual operatingdevicesfor a controlling rope or ropes. In the specific illustration shown thesame consists of a lever 10, rigidly secured upon a shaft 11, whichshaft is journaled in brackets secured to the bot- "11 is a lever 12.

tom of the car, and also mounted on this shaft 13 and 14 designate tworunning controlling- 9o ropes. Each of these ropes is rigidly connectedat one of its ends to the lever 12. The

controlling-rope 13 then passes down over pulleys 15 and 23, and thecontrolling-rope 14: passesdown around pulleys 16 and 22. 5 The pulleys15 and 16 are mounted on a lever 17, which is rigidly secured on theshaft 18,

extending from which shaft is an arm 19, which connects by link 20 to abell-crank lever 21, which latter connects to the valvestem. The pulleysor sheaves 22 and 23 are journaled on fixed bearings. From these,a-nd'jhasi rigidlysecured therein a" shaft 2'6, 1
